Answer: n= -20?
Step-by-step:
Simplify both sides of the equation
1/5n+4=0
Then subtract 4 from both sides
1/5n + 4 - 4 = 0 - 4
1/5n= -4
Then multiply both sides by 5
5*(1/5n)=5*(-4)
Answer:
<h2> no, because the remainder is 126</h2>
Step-by-step explanation:
if x+3 is a factor, then -3 is a root of expression, and the remainder would be 0
calculating remainder:
![-3(-3)^3+6(-3)^2+6(-3)+9=-3\cdot(-27)+6\cdot9-18+9=\\\\=81+54-9=126](https://tex.z-dn.net/?f=-3%28-3%29%5E3%2B6%28-3%29%5E2%2B6%28-3%29%2B9%3D-3%5Ccdot%28-27%29%2B6%5Ccdot9-18%2B9%3D%5C%5C%5C%5C%3D81%2B54-9%3D126)
3x9=27
21/3 = 7
so
7+27x9+5
27x9=243
243+7+5
answer is 255
